Battery systems likewise let homeowners store excess solar energy generated during the day and tap it at night to avoid high utility electricity rates. Electrifying a house with solar energy that’s also used to charge an EV, for instance, eliminates fossil fuel costs and greenhouse gas emissions. Why do it: Over time, electrification upgrades are mutually reinforcing. Depending on local utility rates, electric cars and home electrification can also significantly reduce the payback period for solar panels, thanks to savings on electricity costs. The US Inflation Reduction Act restored a 30% tax credit for residential solar systems, and extended the program to 2034. High-efficiency electric induction ranges are 40% more energy-efficient than gas ranges, which are also a substantial source of indoor air pollution. Heat pump clothes dryers are relatively new to the US, but they’re 50% more efficient than conventional electric dryers, the usual alternative to gas dryers. Claire McKenna, a senior associate at the nonprofit Rocky Mountain Institute, recommends starting with heating and hot water that’s “where the bulk of the energy use is in a home and where you’re going to see the most savings.” If your home has wall-mounted gas heaters, the best option is probably what’s called a ductless mini-split heat pump.How it works: For homeowners, it’s a matter of assessing what a house’s current system can handle, deciding which new technologies you want to invest in and planning your upgrades accordingly. As many as 48 million US homes may also need electrical upgrades to handle the increased power demands of solar panels, heat pumps and electric car chargers, according to a 2021 paper by Pecan Street, a nonprofit that promotes building electrification. doi:10.21037/gs.2019.06.Electrifying your home promises to lock in long-term environmental and economic benefits, although the upfront costs can be high and the process complicated.
